Abstract

The invention relates to a method for removing small quantities of water and other possible components from alkali metal amalgam. Said alkali metal amalgam is brought into contact with an element which is not soluble in mercury and the reaction of the water with the alkali metal amalgam and the other possible components is catalysed to form hydroxides and hydrogen. The catalytically active element is selected from, for example, iron, nickel, cobalt, titanium, chrome, molybdenum, stainless steel, tungsten carbide and graphite.
